Community 群体
A community is a social unit of any size that shares common values, or that is situated in a given geographical area (e.g. a village or town). It is a group of people who are connected by durable relations that extend beyond immediate genealogical ties, and who usually define that relationship as important to their social identity and practice. Although communities are usually small, "community" may also refer to large groups, such as national communities, international communities, and virtual communities.
